Docker Security – part 4(Container image)

This is the fourth part of my Docker security series. In this blog, we will cover ways to secure Container images. Following are the other parts (1, 2, 3) Docker image signing: Docker Container images can be stored either in public or private registry. It is needed to sign Container images so that the client knows that image … Continue reading Docker Security – part 4(Container image) →

Docker Security – part 3(Engine access)

This is the third part of my Docker security series. In this blog, we will cover ways to securely access Docker engine. Following are the other parts (1, 2, 4) Docker engine access: Docker engine runs as a daemon and by default listens on the Unix socket, “unix:///var/ run/docker.sock”. Docker start options are specified in “/etc/default/docker”. To allow … Continue reading Docker Security – part 3(Engine access) →

Docker Security – part 2(Docker Engine)

This is the second part of my Docker security series. In this blog, we will cover security features around Docker engine. Following are the other parts(1, 3, 4) Namespaces: Docker makes use of the following Linux kernel Namespaces to achieve Container isolation: pid namespace mount namespace network namespace ipc namespace UTS namespace To illustrate the … Continue reading Docker Security – part 2(Docker Engine) →

Docker Security – part 1(Overview)

There is a general perception that Containers, especially Docker Containers, are insecure. It is true that Containers are not as secure as VM since all Containers in a single machine share the same kernel and compromising one Container can cause host level compromise or compromise with other Containers. There are many ways to harden Containers and … Continue reading Docker Security – part 1(Overview) →

February – A busy month indeed!

Wow, what a busy month this has been!

So I started my new job on February 1st and thus far, everything has been really great.
My new coworkers are very friendly and helpful.

I’ve spent the better part of february, trying to get to grips with the SP network I will be focusing on from now on. Im still not where I want to be yet, but im getting there. One of the guys I will be working very closely with, started cleaning up the network when he was hired 9 months ago and he’s done a really great job with what he’s had to work with.

There are still some work to be done however, which is the very reason they have hired me and another very good friend of mine. A well run network is a dynamic beast which needs to be tamed. On top of that, the company growth has been around 30% a year, so alot of structure and processes needs to come with that growth, which is where I can really make a difference.

I’ve also had the good fortune of being selected as a 2016 Cisco Champion, which was a very nice surprise. I Continue reading

OpenStack on one machine

To learn more about OpenStack cloud management software, a student or research may install OpenStack on a single machine, such as a laptop computer or a virtual machine, and emulate a small datacenter using virtual machines or containers.

Researchers and students may choose from multiple projects that will set up OpenStack on a single machine. Some projects are community-based open-source projects and others are vendor supported projects (while still nominally open-source).

This post is an overview of links and resources to installing OpenStack on one machine.

DevStack

DevStack is a community-driven open-source project that provides scripts and drivers to install OpenStack on a single machine. It includes direction to install on a laptop computer and to install on a single virtual machine. Devstack may also be configured to use LXC containers as compute nodes, or to use nested KVM virtualization for compute nodes.

OpenStack AutoPilot

Openstack Autopilot is the Ubuntu OpenStack installer. It is free as long as you use less than ten machines in your cloud infrastructure. So, most students and researchers will be able to play around with Autopilot for free.

Autopilot will set up an OpenStack cloud using LXD containers. This means that the system can Continue reading

Stuff The Internet Says On Scalability For February 19th, 2016


JPL is firing up their Exoplanet Travel Bureau . Reserve your space now.

  • 200K : msgs send per second through iMessage; 750 million : xactions per week in App and iTunes store; 11 million : Apple Music subscribers; .7c : speed of light in silicon; 1.125Tpbs : fastest ever data transmission; 360TB : Superman memory crystal stores data forever;  $1bn : Uber’s yearly cost for market share in China;

  • Quotable Quotes:
    • Joseph Bradley : “Here is the takeaway. Blockchains must be massively more scalable than the current tech that supports Bitcoin. We start scaling slowly or quickly. And if we choose the latter, it will “require fundamental protocol redesign.”
    • @sigfpe : Nobody knows how to “program” DNA. They just copy-and-paste bits from other organisms. A bit like how most code is built from stackoverflow.
    • @evankirstel : Slack now has 2.3 million daily active users, 675,000 paid seats, and 280 apps in its directory
    • Jonas Luster : Money spoiled blogging. Why? Because people moved from doing great things for money and then talking about them on their free blogs, to people doing nothing but talking Continue reading

MIT’s new 5-atom quantum computer could make today’s encryption obsolete

Much of the encryption world today depends on the challenge of factoring large numbers, but scientists now say they've created the first five-atom quantum computer with the potential to crack the security of traditional encryption schemes.In traditional computing, numbers are represented by either 0s or 1s, but quantum computing relies on atomic-scale units, or “qubits,” that can be simultaneously 0 and 1 -- a state known as a superposition that's far more efficient. It typically takes about 12 qubits to factor the number 15, but researchers at MIT and the University of Innsbruck in Austria have found a way to pare that down to five qubits, each represented by a single atom, they said this week.To read this article in full or to leave a comment, please click here

Worth Reading: The Chase for Network Speed

There is a delicate balance between the cost of building (and operating) a data center and the cost of hauling traffic over a wide area to take advantage of compute and storage resources. As this balance changes, the economics of build versus the cloud will shift. Falling processor prices can reduce the cost of cloud, but it also reduces the cost of local compute at the same time. -via Netcarftsmen
